Overview
Measuring inflation can be a tricky business. While the concept seems simple, a rise in fall of average prices, in practice it is hard to define exactly. For example, the price of the average automobile may have risen over time, but the functionality of automobiles has also changed, so it is not an exact apples to apples comparison. Perhaps the rise in price is more than justified by additional features.
In addition, some measures of inflation are more volatile than others. In an effort to follow the principles of robust statistics, perhaps it is better to focus policy on the least volatile measures of inflations.
